2 Claims.

This invention relates to certain improvements in .hair waving pads for use where a pre-formed tress of hair is subjected to the action of an-exothermic'material contained within the pad, which exothermic material when moistened will, of itself, generate heat sufficient to impart a so-called permanent wave to the pre-formed tress.

My improved hair waving pad comprises an outer wrapper, an envelope containing an exothermic material and having a perforated face, a sealing flap folded over and removably adhered to the perforated face of the envelope for sealing its perforations, an absorbent sheet adapted to be plac ed upon the perforated face of the envelope after the sealing flap has been stripped therefrom, and an inner flap adapted to be folded over onto the moistened absorbent sheet.

The object of my invention is to produce a hair waving pad of the above character in which the step of perforating the envelope containing the exothermic material immediately before the application of moisture thereto, is eliminated,

thus permitting the pad to be shipped with the :face of the envelope already perforated and temporarily sealed.

A practical embodiment of my invention is represented in the accompanying drawing which ,represents an inside plan view of the'pad, the

inner flap and the sealing flap being partly turned back and the perforated face of the envelope being broken away to disclose the-exothermic .material therein. The outer wrapper 1 of the pad is shown as comprising a once folded sheet of impervious material, such for instance as parchment paper, foil, or the like.

The envelope 2 which material 3, such for instance as calcium oxid in powdered form, has. its face perforated as shown at 4-. This BDVGIQJG is also of impervious material, such for instance as foil.

A flap 5 of impervious material, as foil, is

' folded over and adhered to the perforated face f the envelope 2 for temporarily sealing the perforations f. The sealing adhesive may be of some suitable material, such for instance as petroleum jelly,which will not injuriously afiect tress or the exothermic action .of the matcrial within the envelope, when the pad' is in use.

9 and the sealing flap contains the exothermic above described.

March 3,

A sheet 6 ofabsorbent material is shown as a flap projecting from the pad in position to be moistened and then folded over onto the perforated face of the envelope 2 after the sealing flap 5 has been stripped from the perforated face of the envelope.

A sheet 7 of impervious material, such, for instance as foil, is interposed between the envelope 2 and the outer wrapper 1, which sheet is show n l as extended to produce a flap 8 adapted to be folded over onto the flap 5 after the moistened flap 6 has been folded oyer onto the perforated. face of the envelope and the sealing flap has been folded over onto the moistened flap 6. This flap 5 may form an extension of the sheet 7.

The inner flap 8 is perforated as shown at 5 is perforated as shown at 10. The perforations 10 in the sealing flap 5 are shown as being out of alinement with the perforations 4 of the envelope 2.

In practice, the pre-formed tress of hairzj not shown herein, may be moistened either before or after it is wound, with a suitable hair waving solution. The inner flap 8 is turned back and the sealing flap 5 is stripped'i'rom the perforated face of the envelope containing the exothermic material. The absorbent flap 6 is moistenedand folded over onto the perforated face of the envelope. The inner flap 8 and the sealing flap 5 are then folded over onto the moistened flap 6. The pad is then wrapped around the pre-formed tress in the usual manner and the exothermic action starts at once. Heat is thus set up within the pad suflicient to impart a socalled permanent wave to the pre-formed tress without requiring application of heat from an outside source.

From the above description it will be seen that by sealing the perforated faces of the envelopes containing the exothermicmaterial the pads may be shipped in quantities and the exothermic material protected from deterioration by exposure to varying atmospheric conditions until the time comes for using the pads. When it is desired touse the pads, the se g .fiaps are stripped from the perforated faces of the envelopes, as
